Web19 jun. 2016 · Explanation: f (x) means a function of x. In this case the function of x is 3x −5 So if you have f (2) you're applying the function with your value of x as 2, so we simply substitute 2 into the equation where there is an x so in this case: f (x) = 3x −5 f (2) = 3(2) − 5 f (2) = (3 ⋅ 2) −5 f (2) = 6 −5 f (2) = 1 Answer link
